FIR Filter has widespread applications in signal processing such as image processing, biomedical signal processing, high speed communication systems, noise elimination and many more. The speed of FIR filter can be improved with high speed multipliers and with low propagation delay adders. In this paper we will discuss in detail about different reconfigurable FIR filter architectures and propose a karatsuba multiplier . Although all those three FIR filter architectures are reconfigurable but each of them have different complexity based on the way processing elements are implemented. Each of them has its own merits and demerits compared with the other methods. Xilinx 12.1 result shows better time and area reduction for our proposed fir filter implementation
